PPC Hardware Support (Score 2)

I too, find the BeOS's lack of support for G3 puzzling given that Linux can run on G3's. The word from the BeOS FAQ is:

No, the BeOS is not compatible with Apple's "G3" systems. We have requested from Apple the detailed technical specifications we would need to provide support for these systems, and Apple has declined our requests.

Does anyone know if Apple provided said technical specifications to Linux developers? Was all of this information gleaned from reverse-engineering?
